phony monks

well, my buddhism teacher just showed us a person who pretends to be a bikshu (celibate monk) by using the Shih title. he has a wife. im a little ticked of at this notion of fake monks, though i've known about them for a while, and i'm determined to do something about it.

i was thinking about a satire blog of some phony monk who has a wife and a lot of material wealth. the fakeness of him will be extremely dramatized but theres one catch, i dont know if this is bad karma or not. i know it's bad karma for posing as monk or causing people to disbelieve buddhism (but i will emphasize how fake it is) but is it bad karma to make fun of people who are fake monks?
please tell me if i got any of that Shih notion wrong. here is the site that leads to a vast network of other related sites (one of the monks studied at gold mountain!)http://www.dragonflower.org/. the one that my teacher pointed out was Ven. Shih Yin Fa http://www.buddhistchannel.tv/index.php?id=62,5724,0,0,1,0

he is the person whom i am doubtful about, please dont be prejudiced from my opinions. their teacher can be considered as on the traditional path (he wears traditional japanese buddhist clothing and doesnt have the title that asserts his celibacy) but the disciples wear the chinese robes of a celibate monk. some of them may as be celibate and therefore real monks.
